CoCounsel security and proprietary content
CoCounsel serves 1,000,000 users in the legal, tax, and audit sectors. It connects to Westlaw, Practical Law, Checkpoint, and Microsoft 365. Thomson Reuters uses prompting guardrails to ensure responses only draw from verified information. This approach prevents the model from producing objectionable content from the internet. The technology uses zero-retention API calls and encrypts data with TLS 1.2 and AES-256. Thomson Reuters does not use user content or prompts to train its models or third-party LLMs. The system processes all GenAI requests under the identity of Thomson Reuters.
Fiduciary-Grade AI defines the Thomson Reuters standard for high-stakes professions. This standard draws on authoritative, domain-specific content and protects work with rigorous privacy safeguards. The platform manages sensitive work through structural safeguards and subject-matter expert validation. The technology provides answers that professionals can defend by using authoritative content and expert-validated sources. The 175 years of Thomson Reuters knowledge built into the system helps professionals produce work that can be examined, explained, and defended.
Workflow efficiency and professional judgment
Efficiency gains vary by firm. Steven Hicks-Safra at Cole, Scott & Kissane says tasks that took eight or nine hours now take one and a half to two hours. Daniel Olson at Bassford Remele saves six to eight hours of attorney time on any given day. Ted Schaer at Zarwin Baum uses the tool to manage massive amounts of data and respond to client needs in a timelier fashion. Generic AI tools create risk faster than value. Does the reliance on proprietary content guarantee higher accuracy than generalist models?
